To avoid name collisions, private tags should 10# have names which begin with the developer's NetBSD login name 11# followed by a - or _ character (e.g., thorpej_scsipi, 12# thorpej-signal) 13# 14# Any branch or version tag not listed here should be assumed to be 15# private to the developer who created it. It is inappropriate for 16# anyone other than that developer to commit, move tags, or otherwise 17# modify the contents of the branch. 18# 19# Please update this file when a new branch is ready for consumption 20# by folks other than the maintainer, or when the use or status of an 21# existing branch changes significantly. 22# 23# Format: 24# Branch: name of branch 25# Description: Purpose and intention of the branch 26# Status: Active/Terminated/Dormant 27# Start Date: date first instantiated 28# End Date: date it was Terminated/made_Dormant, if any 29# Base Tag: netbsd-1-5-base, etc. 30# Maintainer: Somebody to blame. 31# Scope: Portion of the tree covered. 32# Notes: Various other info, perhaps explanation of special tags, 33# who-may-commit policies, etc. 34# 35# There are four sections to this file: 36# Release branches 37# Individual developers' branches (Active/Dormant) 38# Individual developers' branches (Terminated), and 39# other 40# 41# Entries within each section should be alphabetized. 42# 43 44 45# Release branches: 46 47Branch: comdex-fall-1999 48Description: Special release branch for pre-1.5 release at 49 Fall 1999 COMDEX. 50Status: Terminated 51Start Date: 52End Date: 53Base Tag: comdex-fall-1999-base 54Maintainer: mycroft 55Scope: Entire tree. 56Notes: 57 58Branch: netbsd-0-9 59Description: The NetBSD 0.9 release branch 60Status: Terminated 61Start Date: 62End Date: 63Base Tag: netbsd-0-9-base 64Maintainer: Release Engineering <releng@NetBSD.org> 65Scope: Entire tree. 66Notes: Subsidiary tags of: netbsd-0-9-ALPHA, netbsd-0-9-ALPHA2, 67 netbsd-0-9-BETA, netbsd-0-9-RELEASE. 68 Commits restricted to release engineering. 69 70Branch: netbsd-1-0 71Description: The NetBSD 1.0 release branch 72Status: Terminated 73Start Date: 74End Date: 75Base Tag: netbsd-1-0-base 76Maintainer: Release Engineering <releng@NetBSD.org> 77Scope: Entire tree. 78Notes: 79 Commits restricted to release engineering. 80 81Branch: netbsd-1-1 82Description: The NetBSD 1.1 release branch 83Status: Terminated 84Start Date: 85End Date: 86Base Tag: netbsd-1-1-base 87Maintainer: Release Engineering <releng@NetBSD.org> 88Scope: Entire tree. 89Notes: 90 Commits restricted to release engineering. 91 92Branch: netbsd-1-2 93Description: The NetBSD 1.2 release branch 94Status: Terminated 95Start Date: 96End Date: 97Base Tag: netbsd-1-2-base 98Maintainer: Release Engineering <releng@NetBSD.org> 99Scope: Entire tree. 100Notes: 101 Commits restricted to release engineering. 102 103Branch: netbsd-1-3 104Description: The NetBSD 1.3 release branch 105Status: Terminated 106Start Date: 107End Date: 108Base Tag: netbsd-1-3-base 109Maintainer: Release Engineering <releng@NetBSD.org> 110Scope: Entire tree. 111Notes: 112 Commits restricted to release engineering. 113 114Branch: netbsd-1-4 115Description: The NetBSD 1.4 release branch 116Status: Terminated 117Start Date: 1 Apr 2000 118End Date: 119Base Tag: netbsd-1-4-base 120Maintainer: 1.4 Release Engineering <releng-1-4@NetBSD.org> 121Scope: Entire tree. 122Notes: 123 Commits restricted to release engineering. 124 125Branch: netbsd-1-5 126Description: The NetBSD 1.5 release branch 127Status: Terminated 128Start Date: 20 Jun 2000 129End Date: 26 Jan 2005 130Base Tag: netbsd-1-5-base 131Maintainer: 1.5 Release Engineering <releng-1-5@NetBSD.org> 132Scope: Entire tree. 133Notes: 134 Commits restricted to release engineering. 135 136Branch: netbsd-1-6 137Description: The NetBSD 1.6 release branch 138Status: Terminated 139Start Date: 22 May 2002 140End Date: 141Base Tag: netbsd-1-6-base 142Maintainer: 1.6 Release Engineering <releng-1-6@NetBSD.org> 143Scope: Entire tree. 144Notes: 145 Commits restricted to Release Engineering. 146 147Branch: netbsd-2 148Description: The NetBSD 2 release branch 149Status: Terminated 150Start Date: 23 Dec 2004 151End Date: 152Base Tag: netbsd-2-base 153Maintainer: 2 Release Engineering <releng-2@NetBSD.org> 154Scope: Entire tree.

About 1/2 of the 242 drivers are converted, the remaining 1/2 need more changes. 243 244 As of import this is snapshot of work in progress and so 245 may not compile; in particular the midi changes are very 246 much "in progress". The audio component has been tested 247 and verified to work with emuxki and auvia. There may 248 be a locking issue in the ac97 code at boot. 249 250 The are two locks per device instance, an ISR lock and 251 a character device lock. The ISR lock replaces calls to 252 splaudio()/splx(), and will be held across calls to device 253 methods which were called at splaudio() before (e.g. 254 trigger_output). The character device lock is held across 255 calls to nearly all of the methods, excluding some only 256 used for initialization, e.g. get_locks. This needs to be 257 documented at merge time. 258 259 To test on a multi way x86 system, search for "mpsafe" in 260 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 261 that will acquire the ISR lock (depends on the hardware, but 262 "while true; do mixerctl -a > /dev/null; done" may suffice). 263 Play audio, run lockstat and verify that that there is 264 contention on the ISR lock. 265 266Branch: ad-audiomp2 267Description: Add MP locking to the audio drivers 268Status: Active 269Start Date: 7 December 2008 270End Date: 271Base Tag: ad-audiomp2-base 272Maintainer: Andrew Doran <ad@NetBSD.org> 273Scope: kernel 274Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 275 276Branch: bjh21-hydra 277Description: Simtec Hydra support and ARM SMP in general 278Status: Dormant 279Start Date: 18 Oct 2002 280End Date: 281Base Tag: bjh21-hydra-base 282Maintainer: Ben Harris <bjh21@NetBSD.org> 283Scope: sys/arch/arm sys/arch/acorn32 284Notes: This code was on a branch because it involves changes to 285 cpuswitch.S which would otherwise make merging the 286 nathanw_sa branch difficult. 287 288Branch: chris-arm-intr-rework 289Description: Rework arm interrupt handling code 290Status: Dormant 291Start Date: 11 Aug 2007 292End Date: 293Base Tag: chris-arm-intr-rework-base 294Maintainer: Chris Gilbert <chris@NetBSD.org> 295Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) 296Notes: Rework arm interrupt code to provide a shared set of interrupt 297 routines, and allow improvements to be shared across all arm 298 based hardware. 299 300Branch: gmcgarry_ucred 301Description: Integrate and encapsulate user credentials 302Status: Dormant 303Start Date: 18 December 2002 304End Date: 305Base Tag: gmcgarry_ucred_base 306Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 307Scope: kernel 308Notes: merge pcred and ucred and poolify 309 310Branch: hpcarm-cleanup 311Description: Fix build problems for hpcarm 312Status: Active 313Start Date: 31 July 2007 314End Date: 315Base Tag: hpcarm-cleanup-base 316Maintainer: Robert Swindells <rjs@NetBSD.org> 317Scope: kernel 318Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 319 320Branch: itohy-usb1 321Description: USB stack overhaul, mostly DMA related 322Status: Active 323Start Date: 22 May 2007 324End Date: 325Base Tag: itohy-usb1-base 326Maintainer: ITOH Yasufumi <itohy@NetBSD.org> 327Scope: kernel 328Notes: To check out the kernel source tree, 329 1. check out checkout script 330 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 331 2. update files in the branch 332 sh -e src/sys/dev/usb/filelist 333 334Branch: jruoho-x86intr 335Description: Cleanup and rework the x86 APIC and PIC subsystems 336Status: Active 337Start Date: 17 January 2011 338End Date: 339Base Tag: jruoho-x86intr-base 340Maintainer: Jukka Ruohonen <jruoho@NetBSD.org> 341Scope: kernel 342Notes: This branch aims to cleanup the x86 interrupt routing code. 343 In particular, a new implementation is provided for all 344 elements of the APIC that involve ACPI.

New lock order: [vmpage-lock] -> pmap-lock. 500 Based on the patch from ad@. 501 - Simplify locking in pmap(9) modules by removing P->V locking. 502 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock) 503 to share locks among UVM objects where necessary. 504 - Optimize pmap_remove() with tracking in struct vm_map_entry. 505 - Unify /dev/mem et al in MI code and provide required locking. 506 507Branch: rpaulo-netinet-merge-pcb 508Description: merge in6pcb with inpcb 509Status: Dormant 510Start Date: Wed Feb 01 2006 511End Date: 512Base Tag: rpaulo-netinet-merge-pcb-base 513Maintainer: Rui Paulo <rpaulo@NetBSD.org> 514Scope: src/sys 515Notes: No longer active due to the lack of time. If you plan to 516 continue this branch, sys/netinet/in_pcb.h already contains 517 the proposed structure layout (which was roughly discussed 518 in the tech-net mailing list). 519 I also defined INP_*() macros to mimicate FreeBSD's inpcb 520 locking style, but currently they do nothing and are not 521 yet called at the correct places (needs discussion about 522 kernel fine-grained locking). 523 To continue this branch, one needs to read all the relevant 524 inpcb/in6pcb source files and change the function names, 525 structure names, structure fields according to the new 526 layout (in6pcb is gone). 527 Don't try to build a kernel from this branch because it won't 528 work. The missing pieces required to do a complete build 529 were not committed because they were incomplete and generated 530 panics. 531 You shouldn't need to worry about KAME syncs because 532 they did most of them by now. 533 After the work is done, you are required to test the branch 534 (before the merge to -current) with an interop IPv6 test. 535 More info at: http://www.tahi.org/ 536 537Branch: wrstuden-fixsa 538Description: Fix a number of issues present with Scheduler Activations. 539Status: Active 540Start Date: 15 May 2007 541End Date: 542Base Tag: wrstuden-fixsa-base 543Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 544Scope: src, though all the interesting stuff is in the kernel 545 or lib/libpthread or maybe gdb. 546Notes: This branch is based off of the netbsd-4 branch! 547 This branch is intended to stage improvements for the 548 Scheduler Activations system for NetBSD 4. Improvements 549 include not allocating memory while preparing to tsleep(), 550 reducing inappropriate upcall delivery (hopefully also 551 eliminating the need to mlock stacks), and being 552 able to pthread_kill() running threads. At this date, 553 most goals have been achieved. This branch also includes 554 fixes to gdb to support working with threaded apps. 555 556Branch: wrstuden-revivesa 557Description: Fix a number of issues present with Scheduler Activations. 558Status: Active 559Start Date: 10 May 2008 560End Date: 561Base Tag: wrstuden-revivesa-base 562Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 563Scope: src, though all the interesting stuff is in the kernel 564Notes: This branch is intended to revive Scheduler Activations 565 in -current in the 5.0 era. This branch's main goal is 566 to re-add syscall compatability so that SA-based libpthread 567 programs can run with a -current kernel. 1:1 threading will 568 remain the NetBSD-default. This branch will re-add necessary 569 upcall support, and will also serve as a chance to clean 570 out cruft that had accumulated in the implementation over 571 time. 572 573Branch: yamt-kmem 574Description: 575 - separate kernel va allocation from kernel fault handling. 576 - make kmem_alloc interrupt-safe. 577Status: Active 578Start Date: Sun Dec 9 2007 579End Date: 580Base Tag: yamt-kmem-base3 581Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 582Scope: src/sys (src/common is tagged but not branched) 583Notes: 584 todo: 585 - investigate if PMAP_PREFER equivalent can be done 586 with vmem_xalloc. find a tester with hardware for it. 587 - g/c replaced code, including kmapent and malloc. 588 - consider to remove other submaps. eg. mb_map 589 590Branch: yamt-nfs-mp 591Description: make nfs client mp-safe 592Status: Active 593Start Date: Sun Apr 27 2008 594End Date: 595Base Tag: yamt-nfs-mp-base11 596Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 597Scope: src/sys (src/common is tagged but not branched) 598Notes: 599 600Branch: reinoud-bufcleanup 601Description: implement and evaluate struct buf usage cleanup strategies. 602 Ideas currently in mind (preference for b): 603 a) 604 1. use of bio_ops per buffer. 605 2. allow chaining/overloading of functions in bio_ops 606 and provide some private context. 607 3. extend the bio_ops with commonly used functionality 608 like pending action counting, custom context passing, 609 last minute processing of buffer data, buffer cache 610 etc. 611 4. investigate the use of the kcont() 612 continuation-passing framework for async io 613 completion notification for bufs 614 ... 615 b) 616 1. all sequencing use of B_CALL replaced by 617 device-threads, if possible generic code around BUFQ 618 2. possibly use kcont() for async IO finished signaling 619 3. counter of pending and queued actions requestable 620 by IOCTL interface?

In terms of UBC, the primary cache for 1332 file data is the VM cache, which needs to operate 1333 in terms of VM pages. As no existing device has native 1334 pages the same size as our VM pages, there already is 1335 a mapping going on between the VM system and the 1336 underlying blocks. So it would be easier and cleaner 1337 to adjust that to deal w/ different block sizes. 1338 Also with UBC, all i/o is in terms of bytes at an offset 1339 with a certain length, so the exact block size isn't a big 1340 deal. 1341 1342 Any other wrstuden-devbsize tag may (and should) go away. 1343 1344Branch: yamt-idlelwp 1345Description: idle lwp, and some changes depending on it. 1346 1347 1. separate context switching and thread scheduling. 1348 (cf. gmcgarry_ctxsw) 1349 2. implement idle lwp. 1350 3. clean up related MD/MI interfaces. 1351 4. make scheduler(s) modular. 1352 1353Status: Terminated; merged to -current 1354Start Date: Fri Feb 17 2007 1355End Date: Thu May 17 2007 1356Base Tag: yamt-idlelwp-base8 1357Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1358Scope: src/sys (src/common is tagged but not branched) 1359Notes: 1360 Status of ports: 1361 alpha [ Done, UP tested, MP not tested ] 1362 i386 [ Done, tested ] 1363 amd64 [ Done, tested ] 1364 mips [ Done, both MIPS1 and MIPS3 tested] 1365 sparc [ Done, UP tested, MP might have 1366 some problem after newlock2 merge ] 1367 sparc64 [ Done, tested ] 1368 arm [ Done, SA1 tested.
